Deflating-tool for pneumatic tires.



J. S. WILEY. DEFLATING TOOL FOR PNEUMATIC TIRES.

APPLICATION FILED JULYIY, 19I4- Patented May 18, 1915 EI MIQQQQO cbGQEOIIIlQd ofresilient metal or th citizen of the 1 1 {states residiigst Hillsboro, in the co i f Montgomery and State of Illinois, haveinvented certain new and useful improvements in Defiating-Tools forPneumatic Tires; ans. 1 do hereby dc clare the following to be a full,clear and exact description of the invention, suchas Will enable othersskilled in the art to which it appertains to maize and. use the sense:lhis invention co orehends certain new and useful lDEfJZCYci his indeflating tools for pneumatic 'res and has for its primary object toprovide tool of this character which may be real; v applied to the vstem and engaged "h the tube within which the valve and valve stem arepositioned to hold the tool against movement during the operation ofdeflating the the This invention has for another object to provide atool of this character which will be of such construction that it may bereadily applied to the tube regardless of the size thereof and engagedagainst the valve stem to retain the valve in spaced relation with itsseat to permit the air to escape from the tire.

The invention has for another oh ect to provide a tool of this characterWhi whereby the clamping arms will reao automatically adgust themselvesto 1\ of the tire tube Within which. the deflating is positioned to holdthe tool against movemcnt after the working end thereoi has been engagedwith the valve stem to retain the valve against inoveincut a; d therebyprevent the valve from retirning to its seat While the tool isinposition.

The invention has for a further object to generally improve andsiinplifydevices of this character and increase the efhciency thereof withoutmaterially increasing the cost of the same.

With these and other objects in view as Will become more apparent thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as wili hehereinafter more fully described and claimed.

For a complete understanding of my invention, reference is he had to thefollowing description and accompanying drawings, in Which- Figure 1 enelevationai view of an thereto, retain the valve nbe in operativeposition, Fig. 2 longitudinal section on the plane or line of l, andFig, 3 is a detail perspective view of the tool removed.

' in erring in detail to the drawings by nu morals 1 de ignates the stemof my improved tool which has its parallel portions inclcssd by e sleevewhile its upper or outer end is turnedat a right angle, and directeddownwerdiy and inwardly parallel with main portion of the stem 1 asshown at 3 and 4: and finally turned outwardly to iorn'ithe valve stemengaging fin- Wie tool termed of a single piece of Wire or otherresilient metal bent centrally upon itself to increase the strength ofthe tool the portions 1, 2, 8 and 4: being formed oi: the: parallel legsof the Wire, as Will be readily understood by referring to the draW-ing". will also he understood that the central when of the Wire "formsthe finger 4 an the oa lei portions oi the Wire formthe body 1 are inproper posiand held in engagement with one any the sleeve which issecurely around the stem 1 or the tool.

he tree extremities of the Wire forming the tool are extended beyond thelower or oi the sleeve 52 and bent at right inner end l to form clampingarms 6 having portions curved outwardly in ctions for clamping engageop,ositc c went around the valve tube 7 of a pneumatic tire or the like toholdthe tool in proper position upon said tube with the valve stemengafgin finger 5 pressing against the outer end of the valve stem 8Within said tube 7 and thereby retraining said valve sten1 8 and the v l9 mounted upon the shine in inoperative position to prevent said valve 9from I110. Ward the valve seat 10 provided the 1 in said tube 7 duringthe opera- "ing a tool stem, clamping arms carrie tool in position upona valve tube, the oppoclamping arms 6 will automatically and securelyclamp the tool in position upon either a threaded or smooth tube andupon tubes 7 of various diameters.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in the details ofconstruction, combination and arrangement of parts may be made withoutdeparting from the spirit and scope of the one end of said stem toengage a tube, a valve stem engaging finger carried by the opposite endof said tool stem to retain a valve steni and valve within the tube ininoperative position. 1

3. A device of the class described comprising a tool formed of resilientmaterial and consisting of a stem having clampin arms projectinglaterally from one end or engagement with a valve tube to clamp the siteend of said stem being bent for engagement over the end of the tubeuponwhich the clamping arms are engaged, a valve stem engaging fingerextended from the last mentioned end of said stem of the tool to retainthe valve stem and the valve mounted thereon in inoperative position,and a protecting sleeve engaged around the main portion of said stem ofthe tool.

4. A toolof the character-described comprising a single piece ofresilient metal bent centrally upon itself to place the legs thereofparallel with one another the main portions of said legs forming t estem of the tool, the connected ends of said legs being extended at anangle from one end of said stemand turned parallel with said stem, theconnected ends of said legs being bent to form a valve stem engagingfinger to retain a valve Within a valve tube in inoperative position,the free ends of said legsbeing extended laterally from the opposite endof said stem of the tooland curved in opposite directions to formclamping arms with their free extremities flared outwardly to permitsaid clamping arms to be readily engaged around the tube of theValvrsaid arms serving. to retain the tool in operative position, and asleeve engaged around the central portions of the legs forming the stemto retain said legsagainst spreading.

In testimony whereof I afiix my signature in presence of two witnesses.
